Specification of Letters Patent.

Application filed March 15, 1915. Serial No. 14,456.

To all-117710211. it may concern Beit known that I, ALEXANDER a citizen of Hungary, residing at in the county of Saginaw and State of Michigan, have invented certain new and useful Improvements in Spikes; and I do hereby declare the following to be a full,

tion, such as will enable others skilled in the art to which it appertains to make and use This invention relates to spikes and more particularly to a device of this character especially designed for securing railway rails to ties and for similar purposes. 1

The invention has for its object to provide a spike of improved and simplified construction embodying means for reliably anchoring the spike against removal from the tie or other object into which it is driven.

Another object is the provision of an inn proved railway spike including a tapered shank and a spiral shoulder extending from adjacent the end thereof to a point adjacent the opposite ends, each of the convolntion's of the shoulder being of substantially rectangular formation and constituting anchormg means designed to reliably secure the Y spike against removal.

Another object is the provision of a spike including a shank rectangular in cross scctien and having two of the four faces there of tapered t0 define a cutting edge at one end thereof to facilitate setting of the spike, a pair of oppositely directed shoulders being formed upon the substantially parallel side faces of the shank edgeto further insure against the removal of the spike.

With these and other objects in view, the

invention consists'in the. novel construction,

arrangement and formation of parts as will 'be her inafter spccificallv described, claimed and illustrated in the accompanying drawing, in which: Figure 1 represents a perspective view of the improved spike. Fig. 2 represents a transverse sectional View on the line 2-2 of Fig. 1, and Fig. 3represcnts a transverse secticnal view on the line 33 ofFig. 1.

Referring to the drawing in detail. wherein similar reference numerals designate corparts throughout the several responding adjacent the cutting "iews, the numeral 5 designates the shank having a head 6 at one end thereof includi ig oppositely directed lips T and -S. the

11p 1 having an inclined or beveled under surface 9 adapted for engagement with the inclined upper surface of the base of a rail, and the lip 8 having a plain under surface adaptcd'for engagement with the top surface of a railway tic. The front and rear faces 10 and side faces 11 of the shank are disposed in substantially parallel relation throughout the major portion of their length, head (5 are tapered relatively wide cutting edge 12 at the end of the shankopposite the head 6.

Adjacent their lower extremities the front and rear faces 10 ofthe shank are,. for1ncd with laterally projecting shoulders 13, and the portions l{ of the faces 10 intermediate the shoulders 13 and the cutting edge 12 are tapered.

The side-faces of the spike shank are formed with a substantially spiral shoulder 15 extending-at right angles to said side faces from 13 to a point adjacent the head (i. The spiral shoulder 15 is gradually decreased in pitch toward the headed end of the spike and each convolution thereof is substantially rectangular and is designed to cooperate with the shoulders 13 to reliablysccurc the spike against removal after it has been driven into a tie or other object.

What I claim'is: p A spike including a shank rectangular in cross section having front, rear and side end of the shank faces, the side faces at one being converged to define "a cutting edge,

a pair of oppositely disposed shouldersl rear faces adia and being pend 1 In testimony Wl-ieljOfI; affix in presence of two witnesses. g ALEXANDER MAKLEY.
